Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To prevent an operator from exposing the body to dust or shavings of an object to be cut when cutting a cocreate, a stone material, a metal pipe or the like with a hand-held cutting tool. A dust-removing sheet for an object to be cut is provided between a rotating disc-shaped cutting blade and a main body portion containing a rotation drive source.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a hand-held cutting tool with a dust guard, which prevents an operator from being exposed to dust when cutting concrete, stones, metal pipes, etc. with a hand-held cutting tool.

[0002]

[Prior art]

 Conventionally, when cutting concrete, stones, metal pipes, etc. with a hand-held cutting tool, as shown in Fig. 2, a rotating disk-shaped cutting blade 1 and a main body with a rotation drive source built-in. It is common to perform a cutting operation using a hand-held cutting tool including the body 2.

[0003]

[Problems to be solved by the device]

 However, in such cutting work, the dust 5 composed of dust or chips of the cut object 3 impinges on the worker 5, the work clothes become dirty, or the cut object 3 is a metal such as a cast iron pipe. In the case of pipes, there is a problem that the working environment is extremely bad, because it may be scorched.

An object of the present invention is to provide a hand-held cutting tool with a dust protector which prevents an operator from exposing the body to dust and chips of an object to be cut during cutting work.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention comprises a dust-removing sheet for an object to be cut hung vertically between a rotating disc-shaped cutting blade and a main body portion containing a rotation drive source. Is a means. This prevents the worker from being exposed to the dust or chips of the material to be cut.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall explanatory view showing an embodiment of the present invention, in which a rotating disc-shaped cutting blade 1, a drive source for rotation, and a gasoline engine in this embodiment are incorporated. The figure shows a state in which a dust-removing sheet 6 of an object to be cut is hung vertically between the main body section 2. As a result, the dust 4 composed of the dust and chips of the cut object 1 is repelled by the dust shield sheet 6, and the worker 5 is not exposed to the dust 4.

In the present embodiment, the cutting blade 1 is a diamond saw blade in which a diamond tip of a sintered body containing diamond powder is fixed to the periphery of the base metal. However, the present invention is not limited to this. Needless to say, the same applies to the case of using various metal cutting blades. Furthermore, in this embodiment, an example in which a gasoline engine is used as a drive source is shown, but it is needless to say that the same can be applied to the case where an electric motor, an air motor, or the like is used.

The dustproof sheet 6 to be hung vertically is preferably fireproof and heat resistant, but may be a rubber belt or cloth, and an appropriate material may be selected and used. At that time, the length, width, etc. may be within a range where the dust 4 does not scatter, and can be set to an appropriate size in consideration of workability. Furthermore, when attaching the dust shield sheet 6, it is possible to adopt an appropriate means such as fixing or detaching depending on the material.

[0009]

[Effect of device]

 According to the present invention, the worker is not exposed to the dust or swarf of the material to be cut, and the work clothes are not soiled or scorched. Moreover, the dust of the material to be cut is repelled by the sheet and falls downward so that it does not scatter and the working environment is improved.
